In the forefront of the materials revolution, cork is one of the greenest alternatives there is. Besides being waterproof, buoyant, elastic, fire resistant and unique in its appearance, it is a naturally harvested material, mainly originating in the cork oak forests located in the Iberian Peninsula (Portugal and Spain).
Because it is harvested only from the bark of the cork oak tree (which means the tree keeps on living and helping to clean our air) it is one of the most highly renewable and eco-friendly resources on the planet.
In fact, cork harvesting can help in the fight against global warming. How? At the age of twenty five the tree's bark can be harvested every nine years, for a period of over 200 years. While the cork is growing it is capturing carbon dioxide from the atmosphere. But it gets more interesting: each time the cork is harvested, the tree absorbs more CO2 to aid in the bark regeneration process. This means regularly harvested cork trees store three to five times more CO2 than those left unharvested.
